metalmonkey47 Posted June 17, 2010 Report Share Posted June 17, 2010 What work have you done? Any refreshing of the valvetrain or bottom end? Quote Link to comment
Skib Posted June 17, 2010 Report Share Posted June 17, 2010 depends on alot of things. 1. what is the CR? 2. are you rebuilding the bottom end at all? (and adding stronger parts?) ___2A. if your changing out parts add dished pistons or thicker head gasket to reduce CR. then refer back to 1. 3. are you doing any head work? 4. do you plan on going EFI or carb? ___4A. size of carb/injectors, fuel pump capacity, ect will all play a factor too. 5. methanol injection? 6. Intercooler? Quote Link to comment
datsunaholic Posted June 17, 2010 Report Share Posted June 17, 2010 I'm not sure anyone has actually explored the limits of boost of an A15. 1) Buy a spare engine. 2) Install the turbo setup of your dreams on your primary engine 3) Turn up the boost until the power scares you (as scary as <60WHP can be) or the engine launches the cylinder head through the hood. If the former, you have a nice spare ready to go. If the latter, install the turbo setup on the formerly spare engine, and don't turn the boost up that high. I'm sure there's a nice mathematical formula for figuring this out in a non-destructive manner, but without knowing the particulars of this turbo'ed A15, like combustion chamber sizes (in cc's), piston dish sizes, static compression, turbo size, and the rest of the stuff Skib said too that is an unanswerable question. For a stock A15, the answer is, "not much". Quote Link to comment
datzenmike Posted June 17, 2010 Report Share Posted June 17, 2010 Stock hypereutectic pistons will handle about 7 PSI with extremely short bursts to 9-10. Hyperutectic pistons are the equivalent of glass and are extremely brittle. Detonation, and you will have some detonation will hammer the shit out of them. If going above this get low silicone forged aluminum ones. Quote Link to comment
Mini-L320 Posted June 17, 2010 Author Report Share Posted June 17, 2010 Its a stock motor with 63,000 miles. I can careless if I blow the damn thing. The turbo I got shows .50 for Intake turbine and .63 for exhaust side. Im just doing this to mess around with. Quote Link to comment
Mini-L320 Posted June 17, 2010 Author Report Share Posted June 17, 2010 Would this be a fair question right here: How much boost can I run on a Stock A15 Motor? Quote Link to comment
datzenmike Posted June 17, 2010 Report Share Posted June 17, 2010 I can careless if I blow the damn thing. Read all 7 posts. Your question was answered. You obviously don't care about your rotary motors or looking after them so boost away and blow the fucker up. Be sure to get a vid of it and post on U Tube. Wow. 1 Quote Link to comment
metalmonkey47 Posted June 17, 2010 Report Share Posted June 17, 2010 Seems like a question to be asked on Datsun1200.com Theres plenty of boosted (turbo AND S/C) A15 motors out there. If you don't care if you blow it, give it to me. I'll gladly rebuild it and treat it right. Quote Link to comment
Mini-L320 Posted June 17, 2010 Author Report Share Posted June 17, 2010 I think you guys are taking this a bit serious, I forgot to put a :lol: , meaning "haha Im kidding". "I can careless if I blow the damn thing :lol:" Quote Link to comment
Pumpkn210 Posted June 17, 2010 Report Share Posted June 17, 2010 I too have thought about doing a (Small) turbo on a stock A engine. Was thinkin about runnin no more than 7-8lb on a stock one! From the power difference I have got from the mods that I have done, I would think that would be enough to notice! But if you spend some money on some pistons and lower the CR and Studded the block to hold the head on you should be able to go quite a bit bigger, and cool it if you can! The engines are easy to come across (around here) so blowing it shouldnt be too expensive! I wanna do a draw-thru turbo on an A, someday :cool: But yea bla bla bla dont do it bla your an idiot, bla bla Im scared bla bla :lol: Quote Link to comment

Mini-L320 Posted June 17, 2010 Author Report Share Posted June 17, 2010 I guess I just said something in a totally different way that i didnt want it sound as. But I Have a Suck Thru Setup that I might use. The only thing thats got me thinkin is how will I make the Turbo Manifold. Im just gonna start at like 4 psi and go to 8 psi and see what happens. right now the only thing I do have done is just a Ported out A14 head and ARP head studs. Quote Link to comment

Maby get the pistons shaved if you can and ceramic coated? Not sure of any other cheap ways to lower the CR. Make your own intake mani! Get some big tubing and some flat plate cut out and drill a flange. If you dont have the technology, you can prep it all up and take it to a fab shop and they will weld it up! Make sure to take a head with you and all the hardware to bolt it up so they can weld it straight! Cant wait to hear more, I may have to do it aswell! Quote Link to comment

I've seen videos on youtube with Turbo A15 motor but dont say how much boost they got on them. Well here's some small info on making your own turbo set up. Jason Gray turbo It's for an L16 but a turbo is a turbo, right? fabricating a turbo manifold Quote Link to comment
Pumpkn210 Posted June 17, 2010 Report Share Posted June 17, 2010 Thanks for the helpfull information! I will Definately look into getting a turbo! Quote Link to comment
mr.mk1 Posted June 18, 2010 Report Share Posted June 18, 2010 www.datsun1200.com Lots of Boosted examples and a MASS of information. Quote Link to comment
Mini-L320 Posted June 18, 2010 Author Report Share Posted June 18, 2010 thanks for the info you guys. I'll see if I have some spare time to get a picture of that Suck thru Setup that I have. Right now its mounted on an L18 but I dont have a tranny for it. Didnt the 510's come 4 speed? cause this L18 has a 5 speed tranny installed. Quote Link to comment

Believe it or not the 510 did come with a 4 speed but I can think of at least 5 different five speeds that will bolt up the the stock 510s L16 motor. (some you wouldn't want to but you could) The fact that you have an L18 indicates that the motor was swapped. No L18 ever had a 5 speed installed. A car this many decades old is bound to have been modified or had parts swapped to keep it on the road. Quote Link to comment
Mini-L320 Posted June 19, 2010 Author Report Share Posted June 19, 2010 I'll see if I can get a number out of the tranny maybe someone here can verify it and let me know what Tranny it came out off. Cause If I can get a good tranny for the L18 then I might just bolt it up to my 210 and have a Turbo L18 Suck Threw Setup. That should be cool until I can get a rebuild kit and Fix up my 12A rotary back up. Quote Link to comment
datzenmike Posted June 19, 2010 Report Share Posted June 19, 2010 Easier to post a picture of it to ID. If about 26" it's likely a dogleg, if longer it's likely a truck or Z car 5 spd. Quote Link to comment
Mini-L320 Posted June 19, 2010 Author Report Share Posted June 19, 2010 Im just test fitting First. Thats a chevy 350 Turbo Manifold. They are pretty easy to get. Well I got Lucky, hehe. The turbo might stick out the Hood A tiny Bit, hehe :D Quote Link to comment
Mini-L320 Posted June 19, 2010 Author Report Share Posted June 19, 2010 And thats the A15, I was just cleaning it up to Repaint the Block and Polish The head and all the aluminum pieces. Quote Link to comment
